The Duratec 35 (code-name Cyclone) is a family of automobile engines from the Ford Motor Company. The first version, a 3.5 L V6, appeared in September 2006 in the Lincoln MKZ. Its displacement can be increased to 3.8 liters, meaning a Duratec 38 could come soon after. Mazda calls its version of the Cyclone the MZI.
The Duratec 35 was on the Ward's 10 Best Engines list for 2007.
The Cyclone is an all-aluminum engine based on the Lincoln/Jaguar Duratec 30 DAMB, and includes variable cam timing on the intake side, a feature already found on the Jaguar AJ30 and Mazda AJ versions of the 3.0.
The new heads relocate all accessory drives to the front of the engine with a flush chain drive. Unlike the current Duratec 30 used in most North American Ford application, this engine features direct acting mechanical buckets with shims valve actuation instead of roller finger followers with hydraulic lash adjusters. The new combustion chambers are reshaped as well.
Gasoline direct injection and turbocharging can be added later. A dual-stage variable length intake manifold, centrally-located sparkplugs, and a 10.3:1 compression ratio are other features. The Duratec 35 is ULEV-II compliant and is said to be capable of meeting the PZEV requirement as well.

[edit] Duratec 35
Official SAE certified engine output is 265 hp (198 kW) and 250 ft·lbf (339 N·m) on 87 octane gas, but could reach 300 hp (224 kW) once planned features like gasoline direct injection are added. This is a substantial upgrade in power from the Duratec 30, and bests all competitive engines except the newest version of Nissan's VQ35DE and Toyota's 2GR-FE[1].
The engine is the same exterior size as the Duratec 30, and should be usable in all vehicles currently using that engine and its derivatives. The company expects the engine to be used in one fifth of all Ford products by the end of the decade. Production begins in 2006. The Duratec 35 will replace the Duratec 30 in some applications (notably the Ford Five Hundred) by the end of that year, but the Duratec 30 will continue in production. With the end of the planned Ford/Mercury/Lincoln version of the Volvo V8 announced[2], the Cyclone will likely be called on for even wider duty in high-end models from Lincoln. For this reason, Lincoln is reportedly developing an exclusive 3.7 L derivative of the Cyclone for its models. This engine is scheduled to appear in 2009.
The Duratec 35 displaces 3.5 L (3496 cc/213 in³) with a 92.5 mm (3.64 in) bore and 86.7 mm (3.41 in) stroke. The aluminum block is made by Teksid in Mexico, while the heads come from Nemak in Alabama, and the crankshaft comes from Bharat Forge of India. The engine will be assembled at Lima Engine in Lima, Ohio, with expansion planned in Cleveland Engine Plant #1.

[edit] Duratec 37
A 3.7 L version of the Cyclone is expected for Lincoln cars in 2008. This is said to be Lincoln-exclusive, but rumors of the Ford Mustang using this engine as well are rampant.
